Harmonics at the power supply connection point according to IEC 61000-2-2
Description
IEC 61000-2-2 defines the compatibility level for voltage harmonics for the point of common
coupling (PCC) with the public supply system.
For systems in which converters or other non-linear loads are widely used, a circuit feedback
calculation that takes the individual system configuration into consideration should always be
performed.
The converter with upstream Line Harmonics Filters (LHF) allows adherence to the
compatibility level for voltage harmonics, regardless of what percentage of the overall load is
made up of the converter load.
Note
The voltage distortions behavior in the frequency range of 2 kHz to 9 kHz (IEC 61000-2-2
AMD 1) and from 9 kHz to 150 kHz (IEC 61000-2-2 AMD 2) must be evaluated specifically
for each system as a function of the impedance at the power supply connection point.
